Sub data:
Description: The transducers calibration values are stored in two separate E2-
potentiometer memories on PC 1750 Transducer. All calibration values is also stored
on PC 1672 Control panel.
At system start-up, a comparison test is made to see that they match each other. If
comparison fails, a diagnostic log is written.
What to do:
1.
Perform a Calibration and a PuC. Restart the KION workstation and check
that the diagnostic log is not reproduced.
2.
Replace PC 1750 Transducer if a digit is present in B, C or D.
3.
Replace PC 1672 Control panel.
Fault: Transferred calibration values for the pressure- or flow transducers is not
correct at system start-up (Off to Standby).
Description: The transducers calibration values are stored in two separate E2-
potentiometer memories on PC 1750.
The E2-potentiometer contains both a non-volatile memory and a volatile memory.
At start-up of the system, data in the non-volatile memory (REG0) is transferred to the
volatile memory (WCR) for each transducer.
After the transfer, a comparison test is made between the non-volatile and the volatile
memory to see that the transfer completed successfully. If comparison fails, a
diagnostic log is written.
What to do:
1.
Perform a Calibration and a PuC. Restart the KION workstation and check
that the diagnostic log is not reproduced.
2.
Replace PC 1750 Transducer if a digit is present in B, C or D.
3.
Replace PC 1737 Measuring.
Fault: Gas supply failure during PuC.
Description: Both AIR- and O2 gas supply are disconnected or the gas supply
pressure is not enough when starting the PuC.
Refer to chapter about "Check of control panel settings and of gas supply" during PUC
What to do:
1.
Connect gas supply or increase gas supply pressure. Required gas supply
pressure: 280 – 600 kPa.
2.
Replace PC 1720 Wall pressure.
Fault: "Leakage automatic ventilation" test failed during PuC
Description: The test pressure is 40 cmH2O.
What to do: Refer to section "If the Pre-use check fails" in this chapter and to
information regarding "Leakage automatic ventilation" in chapter "Service procedures",
section "Pre-use check".
